Discovery and/or Reconnection

Hi,

I've got two nodes running and communicating, or rather I did until the
network went down for a long while. Now, I have two independent
clusters of one node each. How do I get the nodes to rejoin into a
cluster? Does this require a manual service restart? The network has
been up and running for an hour now and the logs show no sign of
reconnect attempts.

...Thanks,
...Ken

Yes, currently, the there is no auto join and you simply need to restart the
isolated node so it will join back to the cluster.

Was this perhaps fixed in 0.9? Under 0.8, I saw my client (ie no-data) nodes not reconnecting to the main cluster nodes (ie. data nodes) in they went down and came back up. However, now under 0.9, the client nodes seem to magically reconnect if the data nodes go down and come back.

Or, if 0.9 doesn't fix this (I'd be surprised...it seems to), how should I handle this? Do I still need to restart the client nodes? Or can I catch exceptions and re-connect (which, actually, I was doing under 0.8 and it seemed to work).

Thanks.

Client nodes do reconnect since 0.9.
